摘　　要：文章利用1995～2006年面板数据，分别从全国总量和每镇平均量两个层次，测算全国及东、中、西三大地区小城镇公共基础设施投资与人口非农化的关系，以及公共基础设施投资对人口非农化的贡献弹性。研究发现，无论从全国总量层次还是从镇均层次看，公共投资对非农人口贡献效率均呈中部地区大于东部地区和西部地区的特点。从贡献弹性看，全国总量贡献弹性变化小于镇均贡献弹性，二者贡献弹性均呈下降趋势。建议当前国家的公共基础设施投资重点在中部地区，以提高资金使用效率，推动人口非农化发展；西部地区通过撤乡并镇，扩大小城镇规模，以提高其公共基础设施投资效率和缩小地区差距。Based on 1995-2006 panel data,the essay analyses the relations between public infrastructure investment and small town population's non-agriculturalization at the national level and the three economic regions,and estimates the contribution of public infrastructure investment to non-agriculturalization.The findings show that in terms of both national aggregation and town average,the contribution of public investment to increase of non-agricultural population in the central region was higher than that in the eastern region and western region.The contribution flexibility at the national level was less than that of town average,but both were decreasing.The authors suggest that in order to increase input efficiency and speed-up population's non-agriculturalization,public infrastructure investment should focus on the central region,and the western region may strengthen public infrastructure investment efficiency by expanding the scale of small towns.
